LIGHTING-RING.

To @ZZ whom t may concern:

Be it known that l, RUDoLrI-I HOFFMAN, a citizen ot the United States, residing at Kankakee, in the county of Kankakee and State of illinois, have invented certain new and useful Improvements in Lightinglings, oi which the following is a specification.

'lhis invention relates to the lighting rings used in Wiclless oil burners, as, for example, burners olf' the type shown in Patent No. Lilia-,637, dated September 28, 15215, and

consistinfr or a )luralit f of la fers ot nonthe ring together may consist of a plurality oi itches or staples which are inserted near the i ot the ring and clenched on the inner side of the ring; rlhese staples are arranged in around the ring in such a u'ianner that the opposite ends of each staple lie in substantially the saine vertical planes as the ends ot adjoining staples, the staples being preinfalfiiy inclined at an angle to the vertical. lt will be seen that by this arrangement of the staples the ring is not weakened, as it would be if the staples were arranged end to end around the rin ln the accompanying drawings, Figure l is a. top plan view oit.' a. lighting ring ein bodying the features oi my invention. Fig. i); is a side view. Fig. 3 is a vertical seotional view and illustrates one of the securing nieans used in iny invention.

The lighting ring 1 may be of any suitable material. Herein it is shown as formed of concentric layers of asbestos paper 2, having overlapping ends secured together as by means of wire staples 3 and 4 passed through said overlapping ends. The staples 5 are inserted preferably near the top of Specification of Letters Patent.

the ring and in such a manner that the 0pposite ends of each staple are spaced from the ends ofV adjoining staples, but in the saine vertical plane. lhus the layers of the ring are securely held together at all points throughout its circumference so that vapor is prevented from rising between the layers and the oil is caused to rise uniformly.

It will be seen that by the use of staples, arranged in the before-mentioned manner, I provide a lighting ring which is not Weakened by said staples, and which possesses a 6l periphery tightly secured at all points. The ring is simple yet very strong and durable. Also the manufacturing costs are cut down Without producing an inferior ring.

I claim as my invention: 7(

l. A lighting ring for Wickless oil burners comprising a body in ring forni consisting of a plurality of concentric layers of sheet material, and staples securing said layers together, said staples being inclined 75 relative to each other and arranged in series around the periphery of the ringso that the upper end oit one staple Will be in the saine vertical plane as the lower end of'an adjacent staple.

2. ln a lighting ring for Wiclless oil burners coin arising concentric layers of noncombusti le .fibrous material, a plurality ot.' binding staples uniting said layers and regularly spaced about said ring with their opposite ends traversing said layers in tivo lines spaced substantially apart and parallel to the top oi.2 said ring, said staples being inclined so that the adjacent ends of proximate staples lie substantially in the saine vertical line.

$3. In a lighting ring for wickless oil burners formed of a. fibrous material such as bestes, a series of staples arranged circum ferentially of the ring and with their legs extending through the ring at points spaced a substantial distance apart so as to avoid a weakening ol the ring, but with their yokes lying against the4 periphery of the ring rela-tively disposed in inclined parallel relation so as to permit of uniform capillary action throughout the circumference of the ring.

In testimony whereof, I have hereunto set m lia-nd.
